Conic Lessons
This is an online lesson that is easily transferable to lecture notes. It reads like a textbook with lots of examples and explanations. It starts with circle and moves through hyperbola, including intersections of conics and conics with linear graphs.

Making Connections: Matrices, Graphs, and Linear Systems
Students will use graphing calculators to solve systems of linear equations in two ways. They will solve systems of equations by writing related matrices and solving by using inverse matrices.

Chicago Public Schools
Thorough treatment of linear programming with three days of instruction. See days 25-27.

The Busing Problem (Linear Programming)
Real life linear programming problems in a lesson plan from PBS. It has an online video that can go with the lesson, but the print material stands alone.

Linear Functions - Learn Your Lines
Students will collect and analyze data using motion detectors of the TI Calculator-Based Laboratory (CBL) to solve and describe if and where data, representing two straight lines, intersect using numbers, symbols, and graphs.

Supply and Demand - An Application of Linear Equations
This grades 8-11 activity focuses on having students create and solve a system of linear equations in a real-world setting. By solving the system, students will find the equilibrium point for supply and demand. Students should be familiar with finding linear equations from two points or slope and y-intercept. Graphing calculators are not necessary for this activity, but could be used to extend the ideas found on sheet 3.

Linear Programming Lessons
Linear programming online lesson with example problems and good graphs. It includes an interactive quiz at the end.

Concise Explanation with Vocabulary
This is linear programming in a nutshell. It has all the background definitions and procedures on how to solve problems with this method.

Self-Check Quizzes

3D Graphing
This is Prentice Hall's self-check quiz for 3d graphing. Enter Web Code: aga–0305

Interactive Pan Balance
This interactive pan balance allows numeric or algebraic expressions to be entered and compared. You can "weigh" the expressions you want to compare by entering them on either side of the balance.
